T 0 all whom it may con-061m:

Be it known that we, DOUGLE M. SALTER and Sos'rHnNn RoBioIrAUx, citizens of the United States, residing at Saratoga, in the county of Hardin and State of Texas, have invented certain new and useful Improvements in Cable Clamps, of which the fol lowing is a specification.

This invention relates to new and useful improvements in a cable clamp.

One object of the invention is to provide a clamp designed to be attached to the cable or jack line through which the pump jack is operated inpumping wells. In pumping wells, particularly oil wells, a pump jack is employed which is connected to the pump rod and which is driven from a suitable driving means through a jack line or cable.- This cable is usually in two sections which are connected by the clamp herein described,

through the medium of a hook. These connecting hooks are different lengths so that the jack line may be adjusted in length to control the stroke of the jack and the clamp herein described has been specially designed to facilitate this adjustment in the manner hereinafter described.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a side view of a pump jack, showing the same connected to the pump rod and to the driving apparatus.

Figure 2 shows a side view of the clamp and connecting cables.

Figure 3 shows a plan view of the driving means for operating the jack.

Figure 4 shows an end view of the clamp.

Figure 5 shows a plan view, and

Figure Gshows a side view of the clamp.

Referring now more particularly to the drawings, the numeral 1 designates a well and the numeral 2 designates a pump jack which is connected to the pump rod 3. The numeral 4 designates a jack line or cable and the numeral 5 designates the clamp which is attached to the free end of said,

cable. The numeral 6 designates an eccentric power wheel which is driven in any suitable manner and which has a ring 7 therearound which does not rotate with the wheel but which is oscillated back and forth as the wheel rotates. This ring has a stirrup 8 to which the power cable 9 is attached at one end and this cable is attached to the clamp 5 by means of a hook 10. The numeral 11 refers to a post having an anchor 12 projecting therefrom provided with a head 13. The clamp 5 is formed of the lower and upper clamp members 1 1 and 15 which are secured together by means of suitable bolts 16 so that they may be readily released by unscrewing the nuts 17. These clamp members have coinciding grooves which form the central opening 18 and the side openings 19, 19 when the clamp members are fitted together. As before stated, the free end of the jack line 4 is attached to the clamp 5. This is accomplished by passing the end of said line through the central opening 18. A clevis 20 is attached to the clamp. The arms of this clevis pass through the side openings 19 and have the enlarged heads 21, 21, to prevent its detachment from the clamp. The outer end of the clamp member 14 has the upstanding fingers 22, 22 which are spaced apart.

In connecting up the pump jack the hook 10 is attached to the power cable and is engaged in the clevis 20 and the oscillation of the eccentric 6 will operate the jack to pump the well. It is usually necessary to adjust the length of the cable connecting the power with the jack so as to give a proper stroke of the pump and for this reason the hooks 10 are made in different lengths. After the jack is started to working, if the stroke is not the proper one, the hook 10 is taken out and one of different length substituted. In doing this, upon upstroke of the pump, the anchor 12 is dropped in between the fingers 22, the head 13 engaging therewith and at the same time the I hook is disengaged from the clevis 20. The jack is thereby stopped and held in fixed position but the power wheel 6 continues to rotate. Another hook 10 of proper length is then substituted and upon forward stroke of the power wheel 6 this hook is engaged in the clevisQO and the clamp at the same time quickly disengaged from the anchor 12 and the pumping process is thereby resumed.

What we claim is A line clamp formed of two sections, means for clamping the same to a line, a lug carried by the clamp and extending at right angles thereto and having a deep our names to this specification in the presnoteh which forms said lug into spaced ence of two subscribing Witnesses.
